Average drive time is 10–11 hours without stops.

• Safety: In winter, snow can affect I-15 through Utah (especially near Cove Fort). Summer: temperatures above 100°F in deserts; check coolant and tires.
• Family stops: Cove Fort (mile 135, Utah) – free historic site with wagon rides. Mesquite, NV has a water park and family-friendly casinos. Baker, CA has the world’s tallest thermometer (134 feet).
• Pet-friendly: Most rest areas have dog runs. Hotels in Las Vegas and Barstow accept pets with fees. In Manhattan Beach, many beaches allow dogs before 9am and after 6pm.

Fatigue Management & Rest Zones

Break at least every 2-3 hours. Stretch at the rest areas in Fillmore (UT), St. George, and Primm. For a longer break, stay overnight in St. George or Las Vegas. If driving straight through, use coffee shops in Beaver or Barstow. The road is relatively straight, so monotony can cause drowsiness; use audio books or podcasts.

Hidden Off-Route Spots

Little-known: the ghost town of Sego, UT (off exit 188) is a short drive to a former mining camp. In California, the town of Amboy (Route 66) has a vintage gas station and Roy’s Motel. Just before Manhattan Beach, the informal “Surfridge” area (abandoned housing development) is a fascinating, eerie stop on the bluffs.

Starting from Salt Lake City, the Wasatch Range dominates the skyline. As you descend south, the landscape transforms from alpine forests to high desert. Near Beaver, Utah’s red rock formations appear. The most dramatic natural attraction is the Virgin River Gorge (mile marker 8-20 in Arizona), with towering limestone and sandstone cliffs.

• Zion National Park (off I-15 exit 40): Consider a 2-hour detour if you have time. Springdale town offers local galleries and restaurants.
• Valley of Fire State Park, NV (1 hour north of Las Vegas): Red sandstone arches, petrified trees, and petroglyphs. Entry fee $10.
• Mojave Desert: Drive through the Mojave National Preserve; wildflowers bloom in spring.

UNESCO World Heritage Sites

Strictly on route, there are no UNESCO sites directly along I-15. However, Zion National Park is part of the Grand Canyon UNESCO area (as a tentative site). A small detour near St. George puts you close. Nearby: Grand Canyon National Park (UNESCO) is a 3-hour drive from Salt Lake City segment. For those interested in UNESCO, consider a side trip to Parowan Gap Petroglyphs (not designated, but culturally significant).
